1. The Global Shift in UPS Energy

  • Data centers demand higher efficiency and sustainability
  • Industry 4.0 & AI require smarter, stable backup power
  • ESG policies push lightweight, low-carbon systems
  • Top brands (Vertiv, Eaton, Delta, Huawei, APC) are launching lithium UPS lines

This isn’t a short-term trend—it’s the next standard in UPS architecture.

2. The Limitations of Traditional Lead-Acid UPS Systems

  • Heavy and bulky; large installation space
  • Low energy density (30–50 Wh/kg)
  • Short cycle life (≈300–500 cycles)
  • Rapid degradation in high temperature
  • Frequent maintenance and costly replacements
  • Contains lead/acid → environmental compliance risks

3. Why Lithium-Ion Is Replacing Lead-Acid

Feature Lead-Acid Lithium-Ion
Energy Density 30–50 Wh/kg 120–250 Wh/kg
Cycle Life 300–500 2000–6000
Weight & Size Heavy, bulky Lightweight, compact
Maintenance High Minimal
Temperature Range 0 ~ 40 °C −20 ~ 60 °C
Installation Fixed Modular, stackable
Environmental Lead/acid Eco-friendly, recyclable

Result: Higher energy, longer life, lower TCO, and smarter control.
